本计画研究一种新提出的混合动力及电动车用无离合器动力换档变速器。其目的是设计新的方法和致动器的电源齿轮变化，以实现最佳性能的CPT，并通过仿真和实验评估系统的性能和响应在稳态和瞬态条件下。预计所提出的变速器将显著降低现代车辆中存在的效率损失，并建立用于实现不依赖于摩擦离合器的档位和模式改变的新技术。预计这些新技术将为开发下一代非常高效的汽车动力传动系统技术提供新的方向。

This project studies a newly proposed clutchless power-shifting transmission (CPT) for hybrid and electric vehicle applications. It aims to design new methods and actuators for power-on gear change to realise the best possible performance of the CPT, and through simulation and experimentation evaluate the system performance and response under both steady state and transient conditions. The proposed transmission is expected to significantly reduce the efficiency losses present in modern vehicles and establish new techniques for achieving gear and mode changes that do not rely on friction clutches. It is anticipated that these novel technologies will provide new direction for developing the next generation of very high efficiency automotive power train technologies.
